The caves are created when a river of water carves out the mud. Skylights are found within the cave were the rooftop soil has eroded or collapsed. Some caves are very short while others extend for thousands of feet. The cave that I entered was so long that, we eventually turned back fearing rainy weather not knowing where the cave might end. Expect to get dirty or dusty and dress appropriately.
It is absolutely essential to bring several light sources either headlamps or flashlights. As with any hike- light snacks, and water are also recommended. Beware of any inclement weather as travel in the mud caves is not advised in the rain. More importantly you should hike with at least one other person or several people if you have the option.
